2誘電体円柱共振器法を用いたAdditive manufacturing向け導電性材料の実効導電率評価

抄録

Effective conductivity of a conductor applicable for an additive manufacturing (AM) might be quite low due to fabrication processes that are coating, plating and inkjet printing, compared as a copper bulk. Therefore, accurate evaluation methods for a low conductivity material are required to improve material characteristic in the frequency band for 5G wireless networks. In this report, we verified usefulness of the two dielectric rod resonator method as a low conductivity evaluation method based on measured results of several conductive materials for AM technology.
